I need to order a top end kit for my 93 polaris sl 750 but the measurements in my repair manual do not match what the cylinders measure at. The cylinders measure smaller than the book shows and they don't match any other engine size shown. My book says 2.774 inches and I am getting 2.744 Why would my cylinders be .030 smaller in diameter than standard stock size? Will I be safe to order a standard size top end kit? I really don't want to have my cylinders bored out. Any help would be appreciated. Thank you.
